Very nice work on the Super Metroid Tricks page, moozooh. Providing smv demos to almost every trick is a great idea. I'm also willing to contribute some of them if it's required.
For now I can suggest the Temporary Blue Suit glitch demo to get the Maridia mainstreet Missile in a NBMB run, since I think it's a interesting glitch, but didn't see it mentioned anywhere in the Tricks Page yet:

Note that this values are the clean ones without any multipliers.
Since most enemies have a damage multiplier of 2, you have to double most damages in order to get the result you will finally see in the memory adress while playing the game. However in special cases, sometimes enemies have a multiplier 1 (standard damage won't change) or 4 to some special damage types (like Ridley has to Super Missiles which do 600 instead of the usual 300 on him), so I think it's best to leave the original damage values and just mention the fact about the multipliers of enemies which increase the actual damage.
